The bag met my needs perfectly, it is for a very light and thin,
yet offers good protection.
I take the Macbook mainly with the backpack / shoulder bag,
Although I would never "throw in the corner" my backpack along with Macbook,
I am concerned about the state of the device but no longer when it is safely stowed in this envelope.
The zipper can not damage the notebook by the way,
as between him and the inner part an extra padding is present.
